Abstract

1. Technical Field

The present invention relates to a pipe for flexibility and external pressure reinforcement when used as a long length in a synthetic resin feed and drain pipe.

2. Purpose of devising

In the case of using a long length of several tens of meters at the site of the synthetic resin pipe for water supply and drainage, a pipe having a smooth inner and outer sides or a corrugated pipe having an inner and outer sides having a corrugated structure is used. The inner surface is to maintain the smooth surface and to form a corrugated structure on the outer surface, but to provide internal and external pressure strength while maintaining flexibility by integrating a plurality of reinforcement in the groove.

3. Composition of the devise

The present invention is designed to integrate a plurality of arc-shaped reinforcing rods 12 in the groove portion 13, while maintaining the corrugated structure in the longitudinal direction on the inner side of the inner surface is smooth, the embodiment of the alternating reinforcement rod 12 'insertion It is designed to be provided with a reinforcement 17 on the inner surface.

4. Effect of the devise

The present invention can be used in the form of rolls by winding each other and transporting them in the form of rolls when transporting them to be used. It is designed to provide economically useful effects.

Description

Flexible and externally reinforced plastic pipes {.}

The present invention is a synthetic resin pipe that is widely used for supply and drainage pipes of 30m / m to 80m / m, especially for long PE pipes. In the past, it uses pipes with smooth inside and outside sides or grooves inside and outside. Corrugated pipe with continuous and protruding parts was used, but smooth pipe uses tens of meters long, which is difficult to wrap due to lack of flexibility, and economical in terms of cost. There is a problem in water supply and drainage, but the flexibility is good, but there is a problem in internal and external pressure, so it is not practical to use the water supply and drainage pipe.

The present invention consists of a smooth surface (15) and the outer surface is a groove (13) and reinforcement in the longitudinal direction to provide flexibility while the internal and external pressure is reinforced so that the water supply and drainage effect is good to solve the above problems (14) is designed to be alternately provided to insert a plurality of arc-shaped reinforcing rods 12 in the groove portion 13 to provide flexibility and internal and external pressure strength.

The present invention is to achieve the above object as shown in Figures 1 and 2, the inner surface is a smooth surface 15 and the outer surface is composed of alternating reinforcement 14 and the recess 13 in the longitudinal direction However, by providing a product in which a plurality of arc-shaped reinforcing rods 12 are inserted into the recess 13, a product providing flexibility and a solution for internal / external pressure reinforcement are provided, and as shown in FIG. When the arc-shaped reinforcing rod 12 'of the groove portion 13 is inserted alternately in a zigzag structure, the product of the present invention promotes the fluidity of PE raw material, and the inner side is smooth while the outer side is corrugated structure (12). (12 ') Insert is economically produced, and as shown in Fig. 3 (b), the cross section of the recess 13 has a semi-circular connecting rod 19, so that the reinforcement 14 is flexible and flexible in the production process. Pipe (11) raw material is configured to facilitate the filling When the invention is described according to the implementation as follows.

Example 1

As shown in Figs. 4 and 5, a reinforcing tool 17 is formed between the inner side 15 and the outer side reinforcement 14 and the recess 13 instead of being filled with PE raw material of the present invention. It is devised to provide internal and external pressure reinforcement in a structural manner, and as an embodiment thereof, a product filled with the raw material of the present invention omits the reinforcement 17 as shown in FIG. 9.10 also provides a reinforcing effect of the present invention. .

Example 2

6, 7, and 8 as the inner reinforcing wall 16 is inserted into the unit, but the reinforcing holes (17) between the reinforcing table 14 and the recess (! 3) of the outer surface is lightweight and Structurally, the role of the arc-shaped reinforcing rod 12 and the integration of the fusion unit 18 are designed to provide flexibility while providing internal and external pressure reinforcement, and as an embodiment thereof, as shown in FIGS. 11, 12, and 13 Arc-shaped reinforcement (12) according to the insertion site, the reinforcement (21) in the longitudinal direction of the black synthetic resin pipe 11 of the present invention by inserting the blue phase differently and devised for providing a variety of products according to the application. At this time, the product of the present invention is provided even if the inner groove 20 or the inner reinforcing bar 22 is inserted in place of the smooth inner surface 15 of the present invention as shown in FIGS. 14 and 15.

The present invention is to smooth the inner surface to facilitate the supply and drainage, and the outer surface of the reinforcing rod 14 and the concave portion 13, but the arc-shaped reinforcing bars (12, 12 ') as a plurality of integrated and flexible It is a product to provide internal and external pressure reinforcement, and in this embodiment, it is excellent in cost reduction due to light weight by forming the reinforcing hole (17), and especially in PE pipe with diameter of about ø30m / m to ø80m / m, It is designed to provide a useful product in the reality that it is wound and moved and released again.

Claims (4)
